The game comes with a set of cards with increasing difficulty. For the highest level of difficulty, there are 20 cards, otherwise every 10 cards. You start with the simple cards, you get a quick feel for the game and win as quickly with increasing difficulty a sense of the complexity.
The vehicles and the small game board are made of sturdy plastic. The size of the game also allows the use as a travel game.
The game is available in different variants. So there is a simpler and a lush equipped variant, but each with the same idea. There are also variants with locomotives instead of cars and other. There is to play with the car if you have played all cards, even 3 extension sets with new cards.
The game is highly recommended and not just for children. Children should, however, be at least 8 to 10 years old, depending on the interest in such puzzle games. (For younger there are still a junior version.)
